The relationship between the ame and the chub is evidenced by similar, stocky body. Categorical requirements towards the environment, and – as it seems – a certain reluctance to adapt allow the ides to inhabit only a limited area of spacious ones, deep, moderately swift sub-mountain and lowland sections of rivers. In spacious and deep waters, it can settle in more monotonous sections, in more spatially restricted areas, it only takes up varied sections, where it has an abundance of places that can serve as shelters. (He adores, as you can see, customs typical and for other members of the family – klenia i jelca.) In summer, herds of ides stop in the open space on the border of quick and quiet sections, in the colder seasons, the activity of the weir gradually decreases; then the herds wander outside the main bed, to quieter episodes, blind legs and deeper, extensive bays. It can live in reservoirs only if their water quality is adequate; it avoids sections with high siltation, and above all, it looks for places, where the underwater vegetation is dense, the water is clear. It is also doing quite well in wider ones, flow (at least partially) drainage channels, where he chooses places with abundant vegetation. It usually persists in oxbow lakes only in the first years, as they age, its condition decreases.
In terms of foraging activity, the ide tries to imitate chub and knows how to persistently, keep looking for food. The smaller mouth, however, does not allow him to absorb such a variety of bites and his menu is dominated by smaller types of water insect larvae, he does not despise soft plants, also collects seeds from the water. In summer, when he has the habit of staying mainly near the surface of the water, he will also not despise terrestrial insects carried by water. Only the largest specimens are prone to predation, and rather sporadically.
The upper limit of the weight of the ame is given as 6-8 kg, but usually no such specimens are found. Even though the ides occur in large numbers in some places, we catch most of the time 1,5-2 kg copies. It grows like a chub, so quite slowly, and only in 10. year of life reaches the length 33-38 cm. Therefore, record ides may have a lush past behind them.
Sexually matures in 3.-4. year, spawning takes place in April–May in numerous groups, very stormy, he spawns on aquatic plants.
Due to the customs of the weir, the most appropriate methods should be fishing with the midwife and fly fishing; it is most effective during the warm season. It follows from Polish experience, that May is the most favorable (25% year-round fishing), and throughout the summer the results are relatively even (May - August; 71% fishing). You can, of course, catch also in the colder seasons peaking – with systematic baiting – relatively good results. In more spacious rooms, moderately fast watercourses can be successfully caught even all winter long, especially effective in overcast and snowfall.
When fishing for weir, however, you have to remember about some peculiarities regarding both the choice of equipment, as well as fishing techniques. The rod should not only be light enough, so that we can fish sensitively, but it should also be soft, preferably with a parabolic action, so that it allows a delicate cut in the fragile mouth of the weir. Longer rods are better, also due to the need to choose the thinnest possible lines – from 0.12-0.15 to 0,18 mm.
The specific technique of fishing is dictated by a certain lethargy of the jib while gaining food. As for the definite ones, we respond with energetic bites of other fish with an equally energetic bite, so sluggish, Barely perceptible taking of the jazz, you have to react with an equally delicate cut. In fact, it's hard to even call it a jam: you just need to hold down the fishing rod, and the hook will easily penetrate the delicate mouth. The method of leading the lure must also be adapted to the lazy approach of the weir to the prey. She's flowing too fast or she won't notice it, or rather he won't bother with her. A lure led too slowly may make him suspicious. In this case, finding the golden mean requires persistent training.
